Making the 130-year-old Severn Tunnel ready for when we electrify the South Wales Mainline

During the six week closure between 12 September and 21 October 2016, our Team Orange engineers worked day and night for an equivalent of 18,000 days to install over eight miles of conductor rail. The newly laid rail will eventually power a new fleet of electric trains through the 130 year-old tunnel, providing more seats and faster, more reliable journeys for passengers.

Over 3,500 people-hours of preparatory work was completed ahead of the six-week upgrade project, which included the removal of over 40 tonnes of soot from the tunnel.
